Coils are wound with pull-in and drop-out voltages. Variations from these pull-in and drop-out figures can be engineered to suit particular applications. This blog post can be used in conjunction with Product Files to identify a solenoid contactor best suited for your application.

This post covers the make and break switch relays covered in the range of auto electrical products at Arc Components Limited. The relays supplied in-store are configured to DIN 72552 terminal standardisation.

A popular historical blog post from October 2010 revisited. The post became an important feature which tried to address bad practices that became apparent particularly within the mobile home and boating communities, highlighting the common misunderstandings of battery connectivity.

This post is dedicated to an acknowledgement that the modern world of information technology and supply chain, circumstances dictate the need to convert wire sizes into a format understandable to UK mechanical engineers, for products not purchased from Arc Components Limited but require additional fittings and components which adhere to the UK and metric standards.

The standardisation definition guide is presented for identification of pin-out configurations on automotive electrical components available at Arc-Components.com. DIN 72552 is used by most high-end component and vehicle manufacturers when creating an automotive circuit.

The battery split charge relay supplied at Arc-Components.com is a high load intelligent voltage sensitive relay unit, fitted between batteries for an efficient way of charging a secondary battery whilst not effecting the charge performance of the primary start battery, designed for effective management of batteries and popular with the mobile home and marine communities, where start battery charging takes priority and once the charge level is up the unit switches over to charge the leisure battery...

Many modern-day indicator flasher units available on the market today can trigger a flashing circuit by pulse switching; old style flasher units (like the tin can type) work differently and contain a bi-metallic strip. The strip is made up of two different conductive metals riveted, brazed or welded together, that when a current is passed through it, the two metals expand and contract at a different rate...

Most fuses used in automotive and domestic application now have standardisation for fuse identification, modern fuses now in production standardise the displayed rating for continuous use, in some cases and in particular glass fuses, the rating on the fuse cap can still be marked with a blow rating.
